This episode explores the extraordinary story of Anna and Artem Doltsev, a Russian sleeper agent couple who lived undercover in Argentina and Slovenia for over a decade. Against the backdrop of the 2022 Russian invasion of Ukraine, their meticulously constructed lives as Maria and Ludwig Munoz, ordinary Argentinian citizens, began to unravel. More significantly, a tip from MI6 led Slovenian intelligence to investigate, ultimately uncovering their true identities through seemingly insignificant details like a family vacation to Russia using diplomatic passports. For instance, a photograph of their wedding found on social media in Russia provided a crucial link. The subsequent raid on their Slovenian home yielded incriminating evidence, including hidden cash and sophisticated technology. The Doltsevs' arrest triggered a major prisoner exchange between Russia and the West, which included the release of Wall Street Journal reporter Evan Gershkovich. This event highlights the ongoing tension between Russia and the West, demonstrating the lengths to which both sides will go to protect their interests and the high stakes involved in espionage. The episode concludes by noting the Doltsevs' transformation into celebrated figures within Russia's intelligence community, showcasing their story as a symbol of Russian patriotism.
